Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
grown on an area of 2.04 million hectares in the world, with production of 2.4 million tonnes
and productivity is 1000 kg ha -1 . Buckwheat is grown for food and fodder in a number of Asian
nations, including India. Buckwheat is primarily grown in the temperate zones of the Northern
hemisphere, particularly in Russia (Oshini, 2004). It's grown in the United States, Canada,
France, Germany, the United Kingdom, Denmark, Poland, the Netherlands, Sweden, Australia,
Bulgaria, Romania, Italy, Japan, South Africa, Brazil, China, South Korea, Nepal and Bhutan.
It is a multi-purpose crop cultivated mainly for grains (11-14 % gluten free protein) for human
consumption, livestock, piggery and poultry feeds, as green manure crop, soil binding crop and
as a smother crop. Except in select areas of Tamil Nadu, farmers in south India are largely
unaware of the crop. Recently it is introduced in the Northern Transition Zone of Karnataka,
hence to know suitable genotypes and nutrition which plays vital role to exploit its fullest
potential is the need of the hour.
Methodology
The experiment was carried out at MARS, UAS, Dharwad during kharif 2021-22. It was laid
out in split plot design with nine treatment combinations and replicated thrice. The treatments
consist of three genotypes viz., G 1: Nilagiri (Dharwad selection-1), G 2: IC-79147 and G 3: PRB-
1 in main plots and three fertilizer levels viz., F1: 100 % RDF (30:15:15 N:P2O5:K2O kg ha -1 ),
F 2: 125 % RDF (37.5:18.75:18.75 N:P 2O 5:K 2O kg ha -1 ) and F 3: 150 % RDF (45:22.5:22.5
N:P2O5:K2O kg ha -1 ) in sub plots were taken. Crop was sown during Kharif 2021 and full dose
of NPK was applied at the time of sowing. The standard procedures are followed to record the
yield and yield observations.
Results
The results of experiment was indicated that among the genotypes, IC-79147 recorded
significantly higher attributes viz., number of clusters planr -1 , number of grains clusters -1 , test
weight and grain yield. Higher yield attributes with IC-79147 were mainly due to a higher
capacity to convert photosynthates from source to sink and a higher yield parameter in IC-
79147 led to a higher grain yield. The genotype IC-79147 was on par with Nilagiri as per as
grain yield was concerned. However, the straw yield was higher with PRB 1 and it was mainly
due long growing period and lower harvest index. Higher net returns were recorded with IC-
79147 as compared PRB 1. Gross returns and the BC ratio showed a similar pattern. Similar
results were observed by Maruti et al. (2018), Among the fertility levels, application of 150 %
RDF recorded significantly higher yield attributes viz., number of clusters plant -1 , number of
grains clusters -1 , grain yield and straw yield and it was on par with 125 % RDF. Higher yield,
yield attributes and economics were due to higher nutrient application which was used by
buckwheat efficiently. Among the interaction effect genotype IC-79147 with 150 per cent RDF
resulted in significantly higher yield, yield attributes and economics.
